High surf warning issued for Saturday
UPDATE: This high surf advisory has been extended to Sunday 6am.
As if on cue for Mavericks, the National Weather Service for the San Francisco Bay Area has issued a high surf advisory starting Friday at 10 pm through Saturday afternoon. They are expecting a northwesterly swell of 15 to 18 feet with periods of 18 seconds. Swell of this size will produce large breaking waves and strong rip currents within the surf zone.
